AI Article Synopsis

  • The involvement of specific brainstem and midbrain areas can lead to different neurological syndromes, including 'one and a half', 'eight and a half', and 'fifteen and a half syndromes'.
  • A recent case study presents 'nine syndrome,' which results from acute pontine infarcts and includes symptoms like internuclear ophthalmoplegia, horizontal gaze palsy, facial paralysis, and motor control issues on the opposite side of the body.
  • The report discusses the origins of these symptoms, reviews variants of internuclear ophthalmoplegia, and examines existing literature on 'nine syndrome.'

Article Abstract

The pathologic involvement of brainstem and midbrain nuclei and white matter tracts in various combinations may result in a spectrum of arithmetically derived syndromes. They include 'one and a half syndrome', 'eight and a half syndrome' and 'fifteen and a half syndrome'. We report a case of 'nine syndrome', which has been reported more recently, caused by caused by acute pontine infarcts and characterised clinically by a combination of internuclear ophthalmolplegia, ipsilateral horizontal gaze palsy, lower motor neuron type of facial palsy, contralateral hemiparesis and hemianesthesia. We highlight the genesis of this combination of clinical signs, revisit the different variants of INO and review the literature on 'Nine syndrome'.
